Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a sword used when a resin is filled into the inside of a hole on the surface of a metal material or the like.

[0002]

[Prior art]

 In recent years, as a measure to prolong the life of water turbines in hydroelectric power plants, repair or repair of damaged parts (with holes) that have occurred on the surface of runners due to cavitation or the like has been performed by welding or thermal spraying.

However, in the welding and thermal spraying processes, deformation of repair parts due to heat input may be a problem, and in some parts, resin is filled in the damaged holes and the original shape is taken. Restoration is also performed to return.

[0004] The filling method is to fill the resin in the damaged part of the holed parts with resin by using a barrel made of metal, bamboo, or rubber to restore the original shape. Since no oil is put in, wasteful work is spent. A conventional construction method will be described with reference to FIGS. 5 (a), 5 (b) and 5 (c). FIG. 5A shows a state immediately before the resin 3a is embedded in the hole 2a using the rubber barrel 1a.

FIG. 5B shows a state in which the rubber sword 1b is moved in the direction of the arrow. However, since the rubber sword 1b does not directly enter the inside of the hole, the resin 3b resists the air pressure inside the hole 2b. The resin coating is formed on the hole 2b without entering the inside. If the resin 3b is dried in this state, as shown in FIG. 5 (C), the continuous film is cut and the bond is lost, and the resin 3c is divided.

[0006]

[Problems to be Solved by the Invention] In the conventional construction using a whirlpool, it is not possible to fill the resin deep into the hole because it is affected by the air pressure inside the hole. Therefore, there is a demand for a filling tool that is effective in discharging air. An object of the present invention is to provide a resin-filling sash capable of filling resin in every corner of a hole without being affected by air pressure inside the hole on the surface of a component.

[0007]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention is characterized in that a rotary roller having a large number of projections for feeding the supplied resin is fed.

[0008]

[Action]

 The resin is supplied to the main body and the resin is guided from the internal passage to the rotating roller. The resin adheres to a plurality of protrusions provided on the rotating roller, and the protrusions carry resin along with the rotation of the roller and feed it from the edge of the hole to be filled into the depth of the hole. At this time, air can escape and the resin can flow to a deep part of the hole. By repeating this, the resin is filled in every corner of the hole.

【Example】

 Hereinafter, the present invention will be described in detail with reference to FIGS. 1 and 2. In FIG. 1, a ball bearing 2 is assembled on a side surface of a box-shaped barrel body 1, and a rotary roller 3 is incorporated with the bearing 2 as a support.

In this mechanism, the rotating roller 3 rotates, and the rotating roller 3 supports the ball bearing 2 so that the supplied resin is smoothly conveyed to the edge of the hole h. Further, a passage 4 for guiding the resin supplied to the main body 1 to the supply port 5 is provided. The rotary roller 3 is provided with a large number of protrusions 6 for feeding the supplied resin into the depths of the holes h scattered on the surface of the component.

Further, when the barrel body 1 is moved in the direction of the arrow, the resin is pushed by the barrel portion 7 outside the barrel body 1 to form a smooth resin film 8. In the figure, reference numeral 9 indicates a handle. Next, the operation of the above configuration will be described. The barrel main body 1 is placed on the holes h scattered on the surface of the component, and the resin is supplied to the resin supply port 5 through the passages 4 in the barrel main body 1.

Holding the handle 9 on the upper part of the barrel body 1, the barrel body 1 is moved in the direction of the arrow while pressing the barrel body 1 against the parts. Simultaneously with this movement, the rotary roller 3 inside the barrel body 1 starts to rotate, and a large number of protrusions 6 provided on the rotary roller 3 enter into the hole h while attaching the resin supplied from the resin supply port 5. The protrusion 6 penetrates deep into the hole h, and the resin adhering thereto is attached to the wall surface of the hole h for filling. Further, the above-described action is repeated by moving the main body 1 in the direction of the arrow, and the resin filling into each hole h is completed. Further, the resin is further pushed by the barrel portion 7 outside the barrel body 1 to form a smooth resin film 8. As described above, in this embodiment, the resin can be filled up to the depth of the hole h even if not a skilled worker. Another embodiment of the present invention will be described with reference to FIGS. FIG. 3 shows a barrel for filling the resin into the relatively shallow hole h. The protrusion 12 provided on the rotating roller 11 has a blade-like shape, and the resin is filled into the hole h by pressing it. FIG. 4 shows a mortar that fills the inside of the deep hole h with resin. The resin is directly supplied to the inside of the rotating roller 13, the resin is discharged from the front end of the protrusion 14 provided on the rotating roller 13, and the inside of the hole h is directly filled with the resin. As another embodiment, there is also a method in which the rotating roller is vibrated finely to more effectively press the resin deeply into the hole to fill the resin.

[0013]

EFFECTS OF THE INVENTION Since the present invention is provided with a rotary roller having protrusions capable of surely filling the resin in every corner of the hole, air is filled when the resin is filled inside the hole on the surface of the component. The holes can be filled with resin without being affected by pressure, and damaged parts can be easily restored to their original shape.
